WebbA hash table (or hash map) is a data structure used to implement an associative array, a structure that can map keys to values. A hash table uses a hash function to compute the index into an array of buckets, or slots, from which the correct value can be found. Webb8 sep. 2024 · A hash table(often called a hash map) is a data structure that maps keys to values. Hash tables combine lookup, insert, and deleteoperations in an efficient way. The key is sent to a hash function that performs arithmetic operations on it. The result (called the hash value or hash) is an index of the key-value pair.

WebbA hash table uses a hash function to compute an index into an array of buckets or slots.

Take a key to be stored in hash table as input. 3.

WebbHash tables get their name from a trick called hashing, which lets them translate an arbitrary key into an integer number that can work as an index in a regular array.
